Acoustics experts - a little help please

Treating ceiling is good, however, with 9' ceiling somewhat less important. In the end acoustic treatments can only do so much, the equipment and recording provide the soundstage/imaging, room treatments simply allow for realizing  full potential of the equipment and recording.

OP, 

Glad you are hearing good results by changing what is between the speakers. Once I start fiddling with the stuff in between my speakers, I realized I could easily hear the hole they created in the sound stage. I motivated me to eliminate the stuff in the center, except the amp and the soundstage filled the space and behind it. It was painful for me, buying a 4 meter expensive pair of interconnects, but worth it. 

Thanks all, 

Spent some time last night moving my speakers around and ended up with a new location much farther out in the room. About a foot more away from the front wall. Another great improvement in depth. Posted a photo on top of my system page. 

My understanding is that first reflections affect sound the most so treating your side walls, ceiling, and floor at these points is important. Rather than putting the cloud directly above your head, I suggest you place it just as you would absorption for the side reflections, which would be in front of you.  Right above your head would likely not take care of the reflection off the ceiling at the listening position. My virtual system has pictures of same. 

@tcutter I love the backlighting too. Very cool. Beautiful room and those measurements are inspiring. Thanks!
